I imagine that in this version of events, Gilgamesh went overboard trying to clean up the mess left behind by the previous king of Uruk; said mess left him with an intensely cynical outlook, particularly when it came to the supposed nature of humans. Enkidu pleaded with him to take a closer look at his own kingdom; only then did Gilgamesh realize how narrow-minded his harsh stance had been.
